Use the graph of below to estimate its domain and range.
If you would like to enlarge the graph or make numbers and letters easier to read, you may click on it to open it in a new window. You may then enlarge that window with your mouse. To further enlarge the image, use your browser’s zoom capabilities. On a PC this is usually ctrl shift + (and zooming out is ctrl -). On an Apple computer this is usually apple shift + (and zooming out is apple -).
a graph of a curve resembling the letter W, except that arrows indicate the arms of the W extend forever up and to the left, and up and to the right; the corners of the W are at (-2,2), (2,5), and (6,1)
The domain is (in interval notation).
If you need to enter , you can type inf or infinity. If you need to union two (or more) intervals, use the letter U. For example, to enter you can type (-inf,5)U(5,10].
The range is (in interval notation).
